To all whom it may concern: Be it known. that I, WILLIAM KATZMANN,

Chicago, in the county ofCook andState of Illinois, have inventedcertain new and useful Improvements in `Fireless Stoves, of which thefollowing is a specification.

The object of my invention is to provide an improved construction oftireless stove or stove of that type that embodies a casing containing anon-conductor of heat in which the'. articles to be cooked are to beplaced after being heated substantially to a teniperature of the boilingpoint of water. In

the heat for the article to be cooked is first generated over gas orother fuel and `is retained by packing the covered food vessel at theboiling point (fora certain length of time) in a boxed stove with thematerial that is a non-conductor of heat.

For a full understandingof the invention and the merits thereof and alsoto acquire a knowledge of tliedetails of construction of thenieans foreffecting the result, reference is to be had to the followingdescription and accompanying drawings, in which: i

Figure l is a perspective view of my improved iireless stove; and Fig. 2is a longitudinal sectional view thereof. Fig. 3 is a fragmentaryhorizontalsectional view illus-- trating the asbestos cylinder composedof asbestos wrapped around itself in successive layers. Correspondingand like arts are referred to in the following description and indicatedin all the views of the drawings by the same reference characters. y

The casing oi' box 1 is divided by a transverse bar or partition 2 intotwo substantially rectan ular compartments 3, and the box is provi edwith lids 4 which'are, in the present instance, hinged at one end andbox by any suitable fastenin means.'

In each compartment 3 is ocated a cylinder 5 which is,^preferably,composed of a sheet of asbestos `wral'iped around itself in successivelayers to form a cylinder, as shown. 6 designates a plurality of bottomdisks the bottom thereof resting upon the bottom Between the outer wallsof the cylinder and the walls of the box 1 mineral wool 7 is stu''edtightly, and a lining 7a of some textile fabric is secured by tacks orother similar fastening means, the upper edges of the fabric extendingoutwardly over 'the upper edge of the cylinders and secured to the wallsof the box and to the sides of the bar 2 so as to retain both thecylinders and ing in every instance in the practical opera-' tion of thedevice lprovided with covers. Preferably cushions 9 stuffed with mineralwool are provided to fit over the covered vessels or utensils.

Each lid 4 is provided with a plurality of cleats 10 and mineral woolpads 11 are stull'ed between said cleats and are retained by textilecoverings l2 secured to the lids. In the preferredforni, helicalspriiigs13 are interposed between the faces of the lids and the pads 11 to pressthe same outwardly so that a tight closure may be effected over thevessels held in the pockets when the lidis secured down upon the box.

A device, such as I have provided by my invention, will be found veryconvenient to the housekeeper who may first, by gas or other fuel heatthe articles to be cooked to the boiling point, and then pack them in myimproved iireless stove and then attend tol other domestic dutieswithout watching the cooking operation. By my invention, also, fuelwillbe saved and I believe that it will prevent overcooking, as one mayheat the contentsof a kettle to the cooking point and place the same inthe tireless stove and leave lthe same cooking for a reasonable period,and upon return, will find ,the food still cooking without danger ofover-cooking The box may be provided with handles as shown, and the lids4 may be secured down upon the box 1 by any desired latch devices so asto maintain the box in a condition to practically exclude air when thelids are closed.

Having thus described the invention, what is claimed as new is:

A stove of the character described, consisting of a box iovided with atransverse bar dividing it into two compartments, a cylinder in each ofthe respective coii'ipartments, each cylinder consisting of an asbes- 5yother and from the'walls of the box, and

Los sheetoolerlupon itself, a plurality of whereby to llold thecylinders and disks in asbestos disks mounted Within. the bottom iplace, and lids for the box. 10 of sach Cylinder, a stufng of mineralWool ln testimony whereof l. a'flx my signature sem-swing the saidcylinders from, each l in presence of two Witnesses.
